New-type floor is composed of three kinds of slabs joined together through fittings. It is a kind of anisotropic two-way slab. In order to study the calculation method of natural frequency, series method, variable thickness method and variable stiffness method are adopted to calculate the natural frequency. The calculation results of three methods are compared with test result and numerical simulation result. The conclusion is that the calculation result of the variable stiffness method is the closest to the real natural frequency of new-type floor.

This paper focuses on finding a more effective bolting design method. Stress and displacement of variable stiffness beam were calculated by using material mechanics, variable stiffness bolting designs was simulated using FLAC5.0 software. The calculation indicates that the maximum displacement of a variable stiffness beam is less than that in a constant stiffness beam, while same material quantity is used; and proper variable stiffness designs can improve the bolting effect while same total quantity of bolts is used according to the simulations.
